1. 16. Modelling aggregate loads in power systems

   University essay from KTH/Elkraftteknik

   Author : Adriel Perez Tellez; [2017]
   Keywords : Load modelling; load aggregation; component-based load modelling; measurementbased load modelling; ZIP load model; Lastmodellering; last aggregering; komponent-baserad metod; mätnings-baserad metod; ZIP last model;

   Abstract : The load response to voltage and frequency changeshas a considerable impact on the behaviour of the powersystem. Thus, the selection of a load model structure andits corresponding parameters is an important task in orderto study and predict the system behaviour. READ MORE

3. 17. Improved Thermal Models for Predicting End Winding Heat Transfer

   University essay from KTH/Elkraftteknik

   Author : Gabriele Luca Basso; [2017]
   Keywords : ;

   Abstract : The thermal analysis is of primary importance for the design of any kind of electrical machine. The cooling has a significant impact on the electromagnetic performances and on the durability and reliability of the machine. READ MORE

4. 18. Thermal Analysis of a Sea Wave Generator

   University essay from KTH/Elkraftteknik

   Author : Ezequiel Quijada; [2017]
   Keywords : sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

   Abstract : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.

5. 19. Advanced metering infrastructure reference model with automated cyber security analysis

   University essay from KTH/Elkraftteknik

   Author : Rikard Blom; [2017]
   Keywords : Advanced Metering infrastructure; AMI; Smart meter infrastructure; smart meter; securiCAD; DSO; Enterprise architecture; system architecture; architecture analysis; cyber security analysis; network security;

   Abstract : European Union has set a target to install nearly 200 million smart metersspread over Europe before 2020, this leads into a vast increase of sensitiveinformation flow for Distribution System Operators (DSO’s), simultaneously thisleads to raised cyber security threats. The in and outgoing information of the DSOneeds to be processed and stored by different Information technology (IT)- andOperational Technology (OT)-systems depending on the information. READ MORE

6. 20. A new programming model for enterprise software : Allowing for rapid adaption and supporting maintainability at scale

   University essay from KTH/Elkraftteknik

   Author : Marc Höffl; [2017]
   Keywords : Enterprise Software; Microservices; Event Sourcing; Command Query Responsibility Segregation CQRS ; Distributed Systems; Process Systems; Enterprise Resource Planning ERP ; Business Process Re-engineering BPR ; Transparency; Adaptability; Testability; Reparability; Seneca.js; Hemera.js; Enterprise Software Patterns; Pattern Matching; Transport Independence; Additivity;

   Abstract : Companies are under constant pressure to adapt and improve their processes to staycompetitive. Since most of their processes are handled by software, it also needs toconstantly change. Those improvements and changes add up over time and increase thecomplexity of the system, which in turn prevents the company from further adaption. READ MORE
